You guys made me remember some games I had forgotten, either because I'm forgetful or because I hate one of the games in the series.
So...

Pokemon Red: God I feel old.

Heroes 3: See above

Fallout New Vegas: I actually started a second playthrough of this not too long ago, which is a first for an open world game (that I have finished anyway).

ME series: I think I played the first one almost three times, not because it's great but because I A: was exited enough about the game to get it on (my brother's) Xbox, and B: actually believed the "stuff will carry over hype". The sequel twice (sure the story is beyond stupid but, it actually has a cool party member). And the third one... Eh, I finished it. That means it can't be that horrible, right guys? Right???
